Find the coordinates of the midpoint for line segment JK if J(-9, 5) and K(21.-7)

Mathematics

Trava [24]3 years ago

Answer:

(6, -1)

Step-by-step explanation:

The coordinates of the midpoint of a line is [(x₁ + x₂)/2, (y₁ + y₂)/2]. For the given line, JK where J = (-9, 5) = (x₁, y₁) and K = (21,-7) = (x₂, y₂).

So [(x₁ + x₂)/2, (y₁ + y₂)/2]

= [(-9 + 21)/2, (5 + (-7))/2]

= [12/2, (5 - 7)/2]

= [12/2, -2/2]

= (6, -1)

Find a8 when a1 = 40,000, r = 0.1
Sindrei [870]

Answer:

a8 = 0.004

Step-by-step explanation:

Q is abt a geometric series given by the eqn: an = a1*r^(n-1)

given a1 = 40000, r = 0.1

an = 40000*(0.1)^(n-1)

a8 = 40000*(0.1)^(8-1)

= 40000*(0.1)^7

= 0.004

3x+7-6=(8/7)-0<br>Value of x?​
ArbitrLikvidat [17]

Answer:

\boxed{\sf x = \dfrac{1}{21}}

Explanation:

\rightarrow \sf 3x+7-6= \dfrac{8}{7}  - 0

simplify the following

\rightarrow \sf 3x+1= \dfrac{8}{7}

subtract 1 from both sides

\rightarrow \sf 3x+ 1 -1= \dfrac{8}{7}   - 1

simplify the following

\rightarrow \sf 3x= \dfrac{1}{7}

multiply both sides by 1/3

\rightarrow \sf 3x \cdot \dfrac{1}{3}= \dfrac{1}{7}\cdot \dfrac{1}{3}

simplify the following

\rightarrow \sf x = \dfrac{1}{21}
